The Texas economy stands as the second-largest in the United States and would rank among the world's biggest economies if it were a country because of its energy sector and technology industry and manufacturing base and healthcare services and international trade.

Geography and Climate

Texas extends across 268,600 square miles (695,600 km²) of land which contains different geographic areas that include eastern pine forests and coastal wetlands and western mountainous regions and desert basins and Hill Country limestone formations and rolling prairies. The state's extensive size becomes evident through its 800-mile straight-line distances which demonstrate its diverse regional characteristics. The state experiences diverse climate zones which range from tropical storm-prone Gulf Coast to alpine conditions in its westernmost mountain ranges and continental conditions in the interior and arid to semi-arid conditions in the western regions.

Population and Demographics

Texas leads the country in population growth through both population growth and migration from within the state and abroad during recent years. The July 2024 population estimate of 31.29 million shows that major metropolitan areas and rapidly expanding suburban counties continue to grow at a steady pace. The state's population growth has created a more diverse age distribution and language base and cultural diversity which solidifies Texas as one of America's most dynamic demographic regions.

Economy

Texas generates a gross state product exceeding multi-trillion dollars which positions it as the second-largest state economy in the United States and ranks among the top economies worldwide when treated as an independent nation. The real output of Texas reached $2.2 trillion in 2024 according to official statistics while nominal calculations show the state's economic value ranges between $2.6 trillion and $2.7 trillion based on specific assessment methods and timeframes. The state economy thrives because of its energy sector which includes oil and natural gas production and wind and solar power development and its manufacturing base and logistics network and information technology sector and aerospace industry and life sciences sector. The oil and natural gas sector generated $27.3 billion in state and local taxes and royalties during fiscal year 2024 which demonstrates the enduring financial value of energy production despite the state's economic expansion into new sectors.

Energy and Power Grid

Texas stands as the leading oil and gas producer in the United States while it advances wind power generation and builds up its solar energy capacity. The state uses the most total energy in the country because of its extensive industrial sector and expanding population while operating its own power grid system through the Electric Reliability Council of Texas (ERCOT). Clean energy production continues to increase rapidly during 2025 as solar power shows significant growth while wind power experiences periodic high points yet natural gas continues to generate the most electricity.

Government and Politics

The capital of Texas is Austin and the state operates under a constitution that sets up a plural executive and a bicameral legislature which meets in regular session every two years. The state policy focuses on creating a business-friendly regulatory framework and low personal tax rates and strong local control which have influenced investment patterns and population shifts that drive metropolitan expansion. (The policy frameworks described here are based on publicly available state information but actual tax details differ between local areas and specific programs.)

Major Urban Areas and Infrastructure

The largest cities in Texas operate as major economic centers which include Houston as the largest followed by San Antonio and Dallas and Fort Worth and Austin with their own distinct industrial profiles. The urban areas link through multiple interstate highways and major international airports and deep-water Gulf ports and rail routes that support North American trade operations. The current population numbers for these cities stand at 2.3–2.4 million for Houston and 1.5 million for San Antonio and 1.3 million for Dallas and 1.0 million for Fort Worth and 0.9 million for Austin while annual population shifts occur because of population expansion and territorial growth.

Education and Research

Texas operates a broad higher-education system which comprises public flagship universities and statewide university networks and multiple nationally recognized private institutions. The major metros benefit from research output in engineering and energy and computer science and biomedical science and space and defense technologies which drives commercialization and workforce development while being supported by a large community college and technical-training system that provides manufacturing and logistics workers.

Culture and Tourism

Texas from the Rio Grande Valley to the Panhandle. The state offers various tourism attractions which include beach activities influences which can be seen throughout its architectural styles and musical traditions and culinary practices and festival celebrations that extend culture emerges from the combination of Indigenous and Spanish and Mexican and African American and German and Czech and American and wine tasting in the Hill Country and historic sites and presidential libraries and Big Bend and Guadalupe Mountains national parks and active arts and music scenes in Austin and Houston and Dallas–Fort Worth and San Antonio.

Housing and Urban Growth

The fast population growth has created higher requirements for housing and infrastructure development while leading to increased discussions about land usage. The largest metropolitan areas maintain strong construction activities while experiencing occasional market declines because of interest rates and construction material expenses and housing market absorption rates yet their affordable housing options and flexible development rules keep attracting people and companies.

Texas History


Early Peoples and Indigenous Cultures

Texas has been home to human populations since 14,000 BCE according to archaeological findings which prove early human settlement in the area. The Clovis and Folsom people hunted large animals throughout the territory before human populations shifted to permanent settlements where they practiced farming and gathering and trading between river valleys and grasslands. The Caddo tribe established itself in East Texas during 800 CE when they constructed mound-based settlements and developed farming practices and extensive trade connections. The region that became Texas supported various native societies including the Comanche and Apache and Karankawa and Tonkawa who developed unique ways to survive in its different environmental areas.

Spanish Claims, Colonial Era, and Transition to Mexico

The first European explorers reached the area during the early 1500s. Spanish explorers charted the coastline while missionaries worked to merge local populations into colonial administrative structures. The Spanish government maintained control of Texas territory through the establishment of missions and presidios and settler colonies during the 17th and 18th centuries. The Mexican nation gained independence from Spain in 1821 which brought Texas under its control. The central Mexican government faced increasing conflict with Anglo-American settlers who received land grants from empresarios because of disagreements about governance and immigration policies and land ownership and slavery practices. The political stability of the region suffered from the continuous changes in immigration and slaveholding regulations that took place during this time.

Revolution and the Republic of Texas

The the prolonged Alamo siege during early 1836 as they fought for Mexican independence. The Battle of0s. The Texas Revolution began when settlers clashed at Gonzales in October 1835 followed by Texas Revolution began when settlers' growing opposition against Mexican rule turned into open rebellion during the mid-183 San Jacinto on April 21, 1836 resulted in a decisive victory for Texian forces under Sam Houston against General Santa Anna's army which secured Texas independence. The Texas Declaration of Independence received approval from delegates on March 2, 1836 which led to the establishment of the Republic of Texas. The new republic operated with limited resources while dealing with internal political disagreements yet it worked to decrease debt and build defenses and attract settlers. The new republic established laws through its constitution which maintained slavery while making emancipation illegal unless Congress granted permission.

Annexation, Statehood, and the Mexican-American War

The United States Congress finally approved Texas annexation through a long-standing discussion in 1845. The United States Congress admitted Texas as the 28th state on December 29 1845 without requiring territorial status. The Mexican-American War began in 1846 after Texas entered the United States because of ongoing border disputes which centered on the Rio Grande region. The Treaty of Guadalupe Hidalgo established U.S. ownership of Texas and extensive Southwest territory after the Mexican-American War. The new state of Texas kept its existing territorial boundaries until it gave away land for railroad development and settlement programs while maintaining control of public lands for domestic growth.

Civil War, Reconstruction, and the Late 19th Century

Texas became part of the Confederacy when it seceded from the Union in 1861 because it served as a vital source of military personnel and resources. The news about emancipation reached Texas late in 1865 which became known as Juneteenth when enslaved people learned about their freedom on June 19th. The post-war Reconstruction period brought federal control to Texas because of ongoing conflicts between racial groups and political and administrative disagreements. The United States readmitted Texas as a state during 1870. The cattle industry together with railroads experienced rapid growth during the late 1800s as Texas ranchers conducted extensive cattle drives toward Kansas rail stations and additional locations. The introduction of barbed wire technology brought an end to open-range grazing which led to faster population growth in settled areas. The 1901 Spindletop oil discovery brought about a new economic period which brought financial success and built new infrastructure while transforming the industrial sector.

20th Century Growth, Challenges, and Modernization

Texas cities experienced rapid growth throughout the 20th century with Houston and Dallas-Fort Worth and San Antonio and Austin showing the most significant expansion. The state economy evolved from its traditional focus on cotton and cattle production to develop petrochemicals and aerospace and electronics and aviation and healthcare industries. The Great Depression together with the Dust Bowl and world wars created significant changes in both population numbers and infrastructure development. The mid-20th century oil discoveries transformed Texas into a leading energy and industrial hub. The political landscape of Texas shifted from Democratic control to Republican dominance during the second half of the 20th century. The state of Texas experienced major social and civil rights movements which affected schools and public facilities and voting processes while mirroring national trends regarding racial equality and governmental control.

Recent Developments and Current State

Texas has maintained its fast growth since the last few decades which made it rank as one of the fastest expanding states regarding population and economic development and cultural impact. The metropolitan areas of Texas function as essential centers for technological advancement and energy production and educational institutions and international business operations. The ERCOT power grid in central Texas operates independently while the state leads the nation in wind and solar power generation despite its dominant position in oil and gas production. The state faces ongoing difficulties in handling water resources and urban infrastructure development and immigration patterns and coping with natural disasters including hurricanes and droughts. The state's past as an independent frontier territory together with its economic strength and complex political nature shapes its modern identity during the twenty-first century.

Texas Geography


Texas ranks as the second-largest state in the United States after Alaska while spanning 268,596 square miles (695,662 square kilometers) of land area which exceeds all European nations except Russia. The southern part of the United States contains Texas which shares borders with New Mexico to the west and Oklahoma to the north and Arkansas to the northeast and Louisiana to the east and the Mexican states of Chihuahua, Coahuila, Nuevo León and Tamaulipas to the southwest. The Gulf of Mexico borders the southeastern part of Texas where the state extends its coastline for 367 miles (590 kilometers). The enormous size of Texas together with its different heights and its position between desert and ocean produces an extraordinary collection of natural landscapes and environmental systems which establish the state as a distinctive region of natural beauty and ecological significance.

Topography and Regions

Texas divides into ten major natural regions known as physiographic provinces which present different geological and environmental features. The Gulf Coastal Plains occupy the southeastern part of Texas which reaches from the Gulf of Mexico into the interior and features level ground with fertile soil and a damp environment suitable for farming and urban growth that includes major urban centers like Houston and Corpus Christi. The Interior Lowlands of Texas extend from east to west through central Texas while featuring prairies and forests and productive agricultural land which includes the Cross Timbers and Grand Prairie regions.

The Edwards Plateau which people call the Texas Hill Country presents itself as Texas' most beautiful area through its combination of rocky hills and clear rivers and distinctive karst geological features. The Great Plains stretch across the western part of Texas from the Panhandle to the Edwards Plateau while providing extensive grasslands and major agricultural production. The Basin and Range Province or Trans-Pecos area in the far west contains three major mountain ranges including Davis and Chisos and Guadalupe Mountains which reach their highest point at Guadalupe Peak at 8,751 feet (2,667 meters). The Gulf Coast marks the lowest elevation point in Texas since it reaches sea level.

Water Bodies and Rivers

The geographical formation of Texas depends heavily on water as a fundamental element. The state contains more than 80,000 miles (128,700 kilometers) of waterways which include the Rio Grande and Red River and Sabine River and Brazos River and Colorado River and Trinity River. The Rio Grande runs for 1,255 miles (2,020 kilometers) through Texas while creating most of the border with Mexico. The water supply for municipalities and irrigation and flood protection and recreational activities depends on the three major reservoirs Lake Texoma and Toledo Bend Reservoir and Lake Travis.

The Gulf of Mexico borders Texas while its coastal region contains barrier islands and lagoons and salt marshes and bays including Galveston Bay and Matagorda Bay and Corpus Christi Bay. These coastal regions protect against tropical storms while providing essential fishery resources. The Balcones Escarpment extends from Del Rio to Waco as a geological fault line which divides the coastal plains from the Hill Country while creating a dramatic ecological and elevation change.

Climate and Weather

Texas features diverse climate zones which match its wide range of geographical areas because the eastern section maintains humid subtropical weather but the western part experiences arid desert conditions. The eastern section of Texas maintains high humidity levels and receives plenty of rainfall while experiencing warm temperatures which create dense forests and abundant vegetation. The central section of Texas experiences a semi-arid climate with hot summer months and gentle winter seasons yet the Trans-Pecos region in western Texas remains dry with minimal rainfall and extreme temperature swings between daytime and nighttime.

The state receives different amounts of rainfall throughout the year because the southeast receives more than 55 inches (1,400 millimeters) while the westernmost areas receive less than 10 inches (250 millimeters). The majority of Texas experiences rare snowfall but the Panhandle and mountainous West Texas areas receive snowfall on a regular basis. The state faces multiple natural disasters because its varied climate produces tornadoes and hurricanes as well as droughts and sudden flood events. The spring season brings frequent severe thunderstorms to Tornado Alley which includes North and Central Texas and Central Texas. The coastal areas of Houston and Galveston face hurricane and tropical storm threats during the period from June through November.

Flora and Fauna

Texas stands as one of the most biologically diverse states in the U.S. because it contains more than 5,000 plant species and almost 800 vertebrate species. The Piney Woods region of East Texas features pine forests that include loblolly and shortleaf pines together with oaks and magnolias and hickories. The central prairies and grasslands support bluebonnets as the state flower and Indian paintbrushes and native grasses including bluestem and switchgrass. The desert-adapted vegetation of the arid western areas consists of cacti and mesquite and creosote bush species.

The western region of Texas is home to white-tailed deer and armadillos and coyotes and mountain lions and bobcats and javelinas. The coastal regions of Texas support a wide range of marine life and migratory birds and alligators while the western mountains provide a habitat for desert and highland species. The state maintains its biodiversity through 14 national parks and Big Bend National Park and Guadalupe Mountains National Park which protect essential habitats and geological sites.

Natural Resources and Land Use

The natural resources of Texas directly relate to its geographical characteristics. The nation's leading oil and natural gas producer Texas operates through its three major basins including the Permian and Eagle Ford and Barnett Shale which power economic and industrial growth. The state holds major deposits of coal and uranium and limestone in addition to its existing natural gas and oil reserves. The state maintains its position as a major agricultural producer through its ranking as one of the top states for cattle and cotton and hay and poultry and corn production. The state leads the country in wind and solar energy production because of its extensive open spaces and plentiful sunlight.

The development of urban areas has transformed specific areas surrounding Texas's major urban centers. The rural areas of Texas maintain their agricultural character through their combination of farms and ranches and natural grasslands. The protection of water resources and preservation of land and defense of vulnerable ecosystems stands as the main focus of ongoing conservation initiatives because of expanding human settlements and industrial activities.
